VAPOR-GASOLENE BURNER.

srEcrFrcA'rIoN forming part of Letters atent'No. 727,087, dated May 5,1903.

Application filed January 2, 1902. Renewed March 24,1903. Serial No.149,396. (No model.)

To all whom it may concern:

Be it known that I, HARRY M. BURNELL, a citizen of theUnited States ofAmerica, residing at Denver, in the county of Arapahoe and State ofColorado, have invented certain new and useful Improvements inVapor-Gasolene Burners; and Ido declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in gasolene-burners more especiallyintended for use on automobiles or horseless carriages, my object beingto provide a device of this class which shall be simple inconstruction,Y

economical in cost, reliable, durable,and thoroughly practicable in use;and to these ends the invention consists of the features,arrangements,and combinations hereinafter described and claimed, all ofwhich will be fully understood by reference to the accompanyingdrawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a top or plan View of my improved burner,shown in det-ail. Fig. 2 is a section taken on the line y y, Fig. 1.Fig. 3 is a section taken on the line z z, Fig. 1. Fig. 4 is a sectiontaken through the combustion-chamber and the outer drum,

showing the cut-olif slide for regulating the draft from below. Fig. 5is a section taken on the line o: w, Fig. 1. Fig. 6 is a section takenon the line P P, Fig. 2.

The same reference characters indicate th same parts in all the views.

Let the numeral 5 designate the body of the burner, which consists of acircular mixing-tube 5, a .straight mixing-tube 5C, and jet-tubes 5d.The straight mixing-tube extends diametrically across the circular spaceinclosed by the circular tube, its intake extremity or nozzle 5g beinglocated between the terminals 5h of the circular tube and communicatingwith two air-ducts 5i, which enter the nozzle from opposite sides, beingformedin theintegral casting which, as shown in the drawings, comprisesthe circular tube,

parts may, however, if desired, be cast in sep- `arate-pieces andfastened together in any suitable manner.

The tube 5c at its extremity remote from the intake or nozzlecommunicates with the circular tube, thechannel being separated by adivider 6, consisting of a plug screwed into the core-hole formed in thecasing opposite the extremity of the tube 5c, the inner extremity of theplug being beveled to form a separate partition. By removing thisdivider free access is obtained to the straight tube for cleaningpurposes. This divider also facilitates the flow of gas from thestraight tube to the circular tube in both directions. (See Fig. 6.) Thejetftubes v5d are mounted above and in contact with the straight tube 5and, as shown in the drawings, extend at right angles thereto. Theextremities of these jet-tubes open into the circular tube, whose outerwalls are also provided with core-openings 4 in line with the jettubeopenings. The core-openings are closed when the device is in use by acircular band 7, extending around the circular tube on the outside andfastened in a manner to be readily detachable,whereby access is gainedto the jet-tubes for cleaning purposes. The upper edges of the jet-tubesproject above the plane of the mixing-tube. These edges are beveled andformed with transverse saw cuts or slots, forming a great many openingsfor the escape of gas, a jet of iiame being at each opening when thedevice is in use. There are narrow longitudinal spaces 8 be tween thefines, allowing freedom of draft from below.

The burner is mounted in a casing 9, supported below the boiler 10, andvits bottom is provided with awire-gauze diaphragm 12 to exclude thedirt, while permitting freedom of circulation of air for draft purposes.

Surrounding and attached to the combustion-chamber is a drum 13, Whosebottom plate 14 is provided with draft-openings. The passage of airthrough these openings is regulated and controlled by a cut-o slide 15,mounted on the drum and having openings arranged to register withv theopenings in the bottom of the drum when the plate is properly adjusted.The draft from below may IOC be entirely cut olf by properly adjustingthe slide 15.

My improved construction possesses a number of advantageous features. Itembodies a considerable length of mixing tube arranged in convenientcompass. The air-ducts 5 with which tubes 16 are connected communicatewith the outer air and allow a steady and uniform introduction of airfor mixing purposes unadected by Winds, gusts, or currents of air. Theair is also hot When it joins the gasolene at the nozzle, having passedthrough a sufficient length of duct for this purpose. The upper edges ofthe jettubes 5 being raised above the body of the burner, prevent theundue heating of the latter.

Having thus described my invention, what I claim'is- 1. Agasolene-burnercomprising a circular mixing-tube and a straight tube extending diametrically across the space in closed by the circular tube, the straighttube having an intake at one extremity and communicating at its oppositeextremity with the circular tube at a central point, and a series ofjet-tubes filling the circle surrounded by the circular tube andcommunicating With the latter at both extremities, the jet-tubes beinglocated above the plane of the straight tube and having gas-outlets atthe top, substantially as described.

2. A gasoleue-burn er comprising a circular mixing-tube,a straight tubediametrically arranged with reference to the circular tube,communicating with the latter at one extremity and having an intake atits opposite extremity, the body of the burner being provided withair-ducts communicating` with the intake extremity of the straight tube,and a series of jet-tubes communicating at their opposite extremitieswith the circular tube and having jet-openings at the top, substantiallyas described.

3. A gasolene-burner havinga circular mixing-tube,astraightmixing-tubediametrically arranged with reference to the circular tubeand communicating with the latter at one extremity, the circular tubehaving an opening in its outer Wallin line with the straightmixing-tube, a plug inserted in said opening and protruding into thestraight tube, forming a separated partition for directing the gas intothe circular tube in opposite directions, and jet-tubes extending atright angles to the straight tube and communicating at both extremitieswith the circular tube, substantially as described.

4. The combination of a mixing-tube arranged in the form of a circleinclosing a space of suitable area, a straight tube diametricallyarranged and communicating at one extremity with the circular tube, theopposite extre mity being the intake for the volatile fluid, a series ofcross jet-tubes communicating at both extremities with the circulartube, and having jet-openings in their upper edges which are beveled,the said jet-tubes being separated by narrow' longitudinal spacespermitting draft from below, a Wire-gauze diaphragm stretched across thebottom of the burner, a combustion-chamber leading upwardly from theburner,and a drum surrounding the burner, extending below the same andhaving a perforated bottom, and a cutoff slide mounted on said drum,substantially as described and for the purpose set forth.

5. A gasolene-burner comprising a circular mixing-tube, a series ofjet-tubes communieating at their opposite extremities Withthe circulartube and having jet-openings formed in their upper edges, the circulartube having core-openings in its outer Wall in line with the jet-tubes,and suitable detachable means for closing said openings, substantiallyas described.

6. A gasolene-burner comprising a circular mixing-tube, a series ofparallel jet-tubes lling the space inclosed by the circular tube andcommunicating at their opposite extremities with the circular tube andhaving suitable jet-openings, the circular tube having core-openings inits outer wall in line With the jet-tube openings, and a band passedaround the circular tube for closing said coreopenings, substantially asdescribed and for the purpose set forth.

In testimony whereof l affix my signature in presence of two Witnesses.
